The beginning of the Eocene Epoch Era.
Answer:
The correct answer is -
Parental genotypes: AO & BO
Children genotypes: AB, AO, BO, and OO
Explanation:
In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.
Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.
The cross depicting the genotypes of children is
IA IO
IB IAIB IBIO
IO IAIO IOIO
In this cross, we get the same result as given in the question -
One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.
Answer:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
Radioactive materials that are high energy and will cause cellular and tissue damage are usually known as ; Alpha radiation.
<h3>
What is Radioactive material and Alpha Radiation ?</h3>
- Chemicals in the class of radionuclides (also known as radioactive materials) have unstable atomic nuclei. They stabilize themselves by altering the nucleus (spontaneous fission, emission of alpha particles, or conversion of neutrons to protons or the reverse).
- For example, the Earth's crust naturally contains the radioactive elements uranium and thorium. These two elements slowly alter their forms over billions of years, leading to the production of decay byproducts like radon and radium. Energy is released during this process. Alpha radiation is one type of this energy.
- Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.
